    Abstract: A tool (16) for the coagulation and dissection of biological tissue including a counter-bearing (35) that has at least one recess (37) open toward the outside and/or one or more hollow chambers (63). The recess (37) or the hollow chamber (63) is configured to provide a force/path elasticity characteristic curve with a plateau-like region II, V, during compression and reexpansion. The path section x in which the elasticity characteristic curve indicates the plateau II, IV preferably is as long as the tissue to be dissected is thick, and is, for example, in the range of 0.2 to 1.5 mm. As a result, the force exerted on the tissue during the cutting operation remains substantially constant in the effective work region.

    Abstract: Devices and methods for delivering fluid to tissue during ablation therapy are described herein. An exemplary device can include an elongate body having an inner lumen, outlet ports, and an ablation element configured to heat tissue. A flow resistance of the elongate body can increase along a length of the elongate body containing the outlet ports in a proximal to distal direction. This can be accomplished by, for example, varying outlet port size or relative spacing, decreasing a cross-sectional area of the inner lumen through which fluid can flow using a flow diverter or tapered inner lumen sidewalls, or limiting a ratio between a total area of the outlet ports and a cross-sectional area of the inner lumen. Adjusting flow resistance of the elongate body can provide more uniform fluid distribution or a desired non-uniform distribution.

Movement of the deployment assembly 24 to a deployed position relative to the body causes a free end of the grasping wire 28 to project out from the annular wall 18 through the aperture 22, and movement of the deployment assembly to a retracted position relative to the body causes the free end of the grasping wire 28 to not project out from the annular wall 18. In the deployed position, the grasping wire 28 may grasp and gather tissue of the leaflet 2,3.

  • Patent number: 10630011
    Abstract: In one example, the disclosure relates to plug connections of conductor tracks of at least two interspaced circuit boards with the aid of at least one plug connector. The plug connections are distinguished, for example, by the fact that the conductor tracks are easily electrically conductively interconnected. For this purpose, the plug connector can be a column having a polygonal or star-shaped or conic-section-shaped cross-section. The column can include at least two C-shaped contact springs positioned opposite each other. Moreover, the interspaced circuit boards each include, at the same point, an opening for partially accommodating the column, including plated through-holes, and so the interspaced plated through-holes of the circuit boards can be electrically conductively interconnected via the contact springs of the column.

  • Patent number: 10617466
    Abstract: A treatment instrument which is used under an environment filled with an electrically conductive liquid includes a probe, a hollow sheath and an insulating member. The probe has a distal portion to chip a treatment target part by ultrasonic vibration and which allows the distal portion to function as one pole in a bipolar electrode. The sheath surrounds the probe. The insulating member covers the sheath except for a partial region on the distal side of the sheath. The partial region on the distal side of the sheath functions as the other pole in the bipolar electrode.

  • Patent number: 10610291
    Abstract: An instrument including working arms and a moveable member. The working arms include a first arm, a second arm, a first electrode located on the first arm, and a second electrode located on the second arm. The moveable member includes a passive circuit element, a first terminal, and a second terminal. The moveable member is moveable to a first position and a second position. In the first position, the first terminal is in electrical communication with the first electrode and the second terminal is in electrical communication with the second electrode so that in the first position an electrical circuit is completed. An impedance is measured of the passive circuit element in the completed electrical circuit. The instrument is adapted to provide a modality based on the measured impedance or a determined position of the moveable member.

  • Patent number: 10433901
    Abstract: Apparatus and methods for ventral only ablation of the tongue, for use in treating sleep apnea and related breathing disorders. An RF ablation probe or wand is inserted in ventral surface of a patient's tongue in a superior plane along a longitudinal (i.e., anterior to posterior) axis of the tongue, to a predetermined depth. The wand is withdrawn, RF energy is applied, creating a lesion predominantly in the interior of the tongue in an anterior to posterior plane, thereby resulting in less scarring but appreciable movement of the posterior tongue base away from the posterior pharyngeal wall. Also disclosed is a tongue retractor device used for measuring the depth of wand insertion, lifting the tongue to expose the ventral surface of the tongue for the procedure, and providing a stop surface to inhibit further wand insertion.
